In wallets for the status of delegated harvesting (started / not started) there is a separate indication. In Nanowallet this is the item “Harvesting status” (Active / Inactive), in NCC the first button changes its name to “Stop delegated harvesting” if the delegated harvesting is started.
On request
http://<ip of any node>:7890/account/status?address=<the address of the account>
you can see remoteStatus - the activation status of the delegated harvesting - is it activated or not.
But how to learn with the help of API whether the delegated harvesting is started or not started? I did not find such a command in the API
